Class 58.30 Reko locomotive

The designation Reko locomotive was introduced in 1957 at the Deutsche Reichsbahn . During the so-called reconstruction - in GDR parlance a synonym for conversion or modernization - the machines were initially upgraded for about two further maintenance sections, and defects that had appeared in operation were to be completely remedied. In most cases it affected the sensitive Wagnerian long-tube boilers with their unfavorable ratio of radiant to tubular heating surface.

history

The term is used for series of steam locomotives of the Deutsche Reichsbahn, in which considerable reconstruction work was carried out to increase performance and to adapt to the fuel situation in the GDR (lack of hard coal suitable for locomotive firing ) as well as to eliminate design errors and war-related "refinements". Repair work was carried out at the same time. The reconstruction also included at least the installation of a new high-performance steam generator. A characteristic feature of these Rekoloks is therefore the combustion chamber boiler with the angular mixing box in front of the chimney. Individual series that had not yet been designed according to the principles of standard locomotives (series 58.30 and 39) were given completely newly built standard driver's cabs instead of the new cab end walls that were always required after the boiler change . Likewise, wheel sets with different wheel diameters have been replaced by those of the standard design (especially with the formerly Saxon 19.0 ). The worn cast cylinder blocks were partially replaced by cylinders in welded construction. In contrast to the reconstruction program of the Deutsche Bundesbahn , the new boilers were not adapted to the respective locomotive series, but the attachment points of the locomotives to the new boilers. The resulting free interchangeability of the steam generator was bought through extensive changes to the locomotive frame. After the renovations, most of the rebuilt series left the workshops with a completely new look. The most striking examples of this are the 01.5 and 58.30 series.

Basically, only selected locomotive series were reconstructed that could not be dispensed with in operational service and that were expected to have a long service life. The donor vehicles for this were mostly locomotives of more recent years of construction or series that were due for refurbishment anyway.

First vehicle that left freight -Lokomotive 50 3501 November 12, 1957 Raw Stendal , which they had been supplied as 50 380 for sale. The first Reko-50, now referred to as 50.35, told you the Bw Güsten to. The last Reko locomotive was the 52 8200, which went into operation on December 23, 1967; the Reko program was initially considered to be over. In 1968, the state and party leadership of the GDR then asked the Reichsbahn to create a strategic reserve of 45 express train locomotives of the 03 series (18 t mean coupled axle driving mass). From 1969 to 1972 are in the Raw Meiningen not only the required 45 but even 52 locomotives of this series with only a few years old Rekokesseln the hitherto largely retired Type 22 (formerly class 39, Prussian P 10 ) been fitted. Due to their age and the very extensive repair and labor requirements of the donor vehicles, the Reko locomotives of the 58.30 series were the most expensive conversions of the entire program.

(Re) built standard gauge locomotives

Machines from the following standard gauge steam locomotive series were reconstructed at the Deutsche Reichsbahn and assigned to a new series or sub-series:

  • 1962–1965: 35 locomotives from the 01 series to the 01.5 series (Raw Meiningen )
  • 1959, 1966: 18 class 03.10 locomotives (Raw Meiningen). The machines of this series kept their original serial numbers, because due to the condition of the boilers made of non-aging-resistant St 47K steel, all existing machines had to be equipped with replica boilers or reconstructed.
  • 1958–1962: 85 class 39 locomotives for class 22 (Raw Meiningen)
  • 1957–1960: 80 class 41 locomotives for class 41 (Reko) (Raw Chemnitz / Raw Zwickau ). These machines also kept their serial numbers because the entire stock was to be re-boiler due to the St 47K boiler.
  • 1957–1961: 208 class 50 locomotives for the DR class 50.35 (Raw Stendal )
  • 1960–1967: 200 class 52 locomotives for class 52.80 (Raw Stendal)
  • 1958–1962: 56 class 58 locomotives for class 58.30 (Raw Zwickau)
  • 1969–1972: 52 class 03 locomotives (Raw Meiningen). These conversions were not officially called reconstruction, as the program had already ended and no new boilers but used Reco boilers were used. That is why they kept their company numbers.

and as individual vehicles for test operation and partly as test vehicles:

The mechanical engineering test and development center in Halle (Saale) was in charge of the reconstruction program .

Further "Recolokomotives"

In addition to the improved standard-gauge steam locomotives, other vehicles were converted under the name "Rekolokomotive". Initially started as the replacement of large parts of worn machines, the program changed for the reconstruction. These copies of the series 99.64-71 and 99.51-60 were de facto new builds, as almost no old parts had been reused. In addition, further individual, technically completely outdated individual vehicles were almost completely rebuilt. Some small locomotives were also included in this program, and in some cases the track width was even changed during the “reconstruction”.
